The case arrived broken. I contacted the seller and he said he will ship another one but then I can't get another reply from the seller to know what the tracking number is. No clue if it's been shipped it's now been 3 weeks. Also took a long time to ship initially. And charged way too much for shipping to Canada. Cost me US$46 and I know that sending it First Class int'l would have cost 22$. The seller was not flexible.
